DENTISTY - Dental Charting Flashcards
What is the canine dental formula?
3-1-4-2 / 3-1-4-3
What is the feline dental formula?
3-1-3-1 / 3-1-2-1
How do you label equine teeth using the Triadan System?
The Triadan System describes each tooth using three digits, with the first digit referring to the quadrant in which the tooth is located. 1 refers to the upper right, 2 refers to the upper left, 3 refers to the lower left and 4 refers to the lower right
What should be done prior to beginning dental charting?
Inspect the lips, mucosa, oropharynx and tongue and note any abnormalities
What are the steps involved in dental charting?
- Note any missing or extra teeth, discolouration or fractures and assess the periodontal structures
- Calculus index
- Gingival index
- Probing
- Peridontal disease staging
Which symbol should you use to mark a fractured tooth in dental charting?
Use a hashtag # to mark a fractured tooth on the dental chart
Which symbol should you use to mark a missing tooth in dental charting?
Colour in the tooth to mark a missing tooth on the dental chart
Which symbol should you use to mark a planned extraction of a tooth in dental charting?
Put a half cross (/) over the tooth to mark a planned extractionon the dental chart, and finish the X once the tooth is extracted
Which symbol should you use to mark a carious lesion in dental charting?
Mark ‘CA’ on the dental chart to indicate a carious lesion
Which symbol should you use to mark a retained tooth in dental charting?
Mark ‘RT’ on the dental chart to indicate a retained tooth. It can also be beneficial to draw where the retaineds tooth is and assign it a number
What is the calculus index?
The calculus index is the grading of the amount of calculus covering the buccal surface of the tooth
Describe the calculus index grading system
0: No calculus
1: Some calculus covering less than 1/3 of the buccal tooth surface
2: Moderate calculus covering 1/3 to 2/3 of the buccal tooth surface with minimal subgingival deposit
3: Heavy calculus covering more than 2/3 of the buccal tooth surface above and below the gingival line
How do you fill in the calculus index in the dental chart?
Fill in the grade number for the appropriate tooth in the row indicated ‘CI’
Describe the gingival index grading system
0: Normal gingiva
1: Mild gingivitis, slight colour change, mild alteration of the gingival surface. No bleeding on probing
2: Moderate swelling and gingivitis. Bleeds on probing
3: Severe swelling and gingivitis. Spontaneous bleeding and possible ulceration
How do you fill in the gingival index in the dental chart?
Fill in the grade number for the appropriate tooth in the row indicated ‘GI’
How do you carry out dental probing?
Use a blunt ended periodontal probe with millimetre markings, and use the tip if the probe to probe gently in 4 to 6 areas around the base of the tooth to measure pocket depth (the gingival margin to the base of the pocket)
What is the normal gingival pocket depth in dogs?
Less than 3mm
What is the normal gingival pocket depth in cats?
Less than 0.5mm
Describe the periodontal disease staging system
0: No peridontal disease
1: Gingivitis only
2: Less than 25% attachment loss, furcation 1 exposure
3: 25-50% attachment loss, furcation 2 exposure
4: More than 50% attachment loss, furcation 3 exposure
What does attachment loss refer to in dentistry?
Attachment loss refers to the loss of the periodontal attachments which support the teeth
What can be used to measure attachment loss?
Pocket depth
Dental radiography
What will the pocket depth be in a patient with stage 2 periodontal disease?
Pocket depth of 4 - 5mm
What will the pocket depth be in a patient with stage 3 periodontal disease?
Pocket depth of 6 - 7mm
What will the pocket depth be in a patient with stage 4 periodontal disease?
Pocket depth of more than 7mm
How do you use dental radiography to measure attachment loss?
Measurement of attachment length using dental radiography involves measuring from the cemetoenamel junction (CEJ) to the tooth root apex to determine the total attachment length. Then measure the distance between the alveolar margin to the cemetoenamel junction (CEJ) to get the value for attachment loss
What does furcation exposure refer to in dentistry?
Furcation exposure refers to the loss of bone and attachment in the area where the roots of a multi-rooted tooth diverge (known as the furcation)
What does furcation 1 (F1) exposure refer to?
Furcation 1 (F1) exposure is where the probe goes into the furcation and up to 1/3 buccolingual crown width of multirooted tooth
What does furcation 2 (F2) exposure refer to?
Furcation 2 (F2) exposure is where the probe goes up to 2/3 buccolingual crown width of multirooted tooth
What does furcation 3 (F3) exposure refer to?
Furcation 3 (F3) exposure is where the probe goes all the way through buccolingual crown width of multirooted tooth
Describe the tooth mobility scoring system
M1: Slight mobility (less than 0.5mm vertical and less than 0.2mm horizontal)
M2: Some mobility (less than 0.5mm vertical and less than 1mm horizontal)
M3: Severe mobility (more than 1mm horizontaln or vertical)
How do you fill in the periodontal disease scoring in the dental chart?
Fill in information about periodontal disease in one of the ‘other rows’ on the dental chart
